| The development and successful implementation of the system has greatly enhanced the quality and speed of the Designing Weaving Plan and the Designing technical chart, this also normalizes process management. Based on the full understanding of Weaving process characteristics in the textile enterprises, based on the principles of software development, I Developed the Weaving process CAD system using object-oriented programming and databases etc. computer technology. The system has used the modular design ideas, with the characteristic of friendly surface, convenient operating, and effect being good for users.Combining to concrete project, the functional modules of the Weaving process CAD system were implemented, and the question related to system running was solved, which were all developed by Delphi 7.0 as application development facility, and Microsoft SQL Server 2000 as Database Management System on Windows Operating System. The dissertation emphasizes the analysis, design and realization of the weaving process CAD system. This dissertation studied the flow of the design and management of the Weaving process, including the business flow and the date flow. To normalize process design as the starting point, the process database is designed as three-layered structure, and user-defined mechanism is introduced into it. This method not only normalizes the processes of the technical, but also enhanced system's generality, and The system is highly expansionary. According to the process database, the system implemented the function of the Designing Weaving Plan, process changing mangement and so on.Finally, the dissertation illustrations several key problems which has been encountered in the proceeding of this system development in detail. The problems involved the safety and speed of the system, the design of the Weaving Plan, static and dynamic purview control and annunciator. Then,summarize research content of the paper and point out the direction of further studying. |
